CAUTION: DO NOT ATTEMPT TO USE THIS EQUIPMENT
WITHOUT FIRST UNDERSTANDING THE CONTENTS OF
THIS MANUAL.
Introduction
Overview of C450/ C625 lift system
Before using this equipment, and to ensure the safe operation of your C450/ C625 lift, carefully read this en-
tire manual, especially the section on “Cautions”. The C450/ C625 is designed to be used in conjunction
with Prism Medical lift track, accessories and slings. Please refer to any user guides supplied with these com-
ponents and refer to them while reviewing this manual.
Should any questions arise from reviewing this manual contact your local authorized Prism Medical dealer.
Failure to comply with warnings in this manual may result in injury to either the operator, or the individual
being lifted/transferred. Damage to the lift and/or related components may also occur. Be sure that the contents
of this manual are completely understood prior to using this piece of equipment.
Store this manual with the documents included with the lift system and sling (s). Contents of this manual are
subject to change without prior written notice.
The C450/ C625 is a lifting aid used by health care professionals and those providing care in the home to lift,
position and transfer clients or a disabled family member. The C450/ C625 lift is part of what is termed ceil-
ing lift technology which takes advantage of lifting from above and not from below or the side. Additionally
the ceiling lift does not take up valuable floor space as most traditional methods do. Finally, the ceiling lift
makes it possible to move mobility impaired individuals with minimal strain or risk to the caregiver, while
providing complete safety, dignity and comfort for the client or family member.
The C450/ C625 lift is one of three major components that make up this technology. The other two compo-
nents are the track and sling. The C450/ C625 lift runs on the lift track which is securely mounted to the ceil-
ing structure of the institution, or home with the use of ceiling brackets. The track itself is made of specially
designed aluminum and comes in many different shapes, lengths and configurations, and is custom tailored and
installed to meet your specific requirements. The third component, the sling, is a specially designed fabric ac-
cessory that attaches to the lift by means of a carry bar and straps, and holds an individual while the lift, posi-
tioning or transfer takes place. Both the track and sling are generally supplied with the lift at the initial time of
purchase. Please refer to any user guides supplied with the C450/ C625 lift and reference them while review-
ing this manual.
The C450/ C625 is a fixed ceiling lift, that is, it always remains on the lift track. It has the ability to lift an in-
dividual up from one location such as bed, move the individual along the track to another location and
finally lower the individual into a chair or bath. It is moved along the track in one of two ways. The first is by
manually moving the lift along the track with the aid of a caregiver. The second is by having the lift power it-
self along the track. The functions of lifting up or down, or moving to the left or right, are accomplished by
pressing buttons of a pneumatically (air) operated hand control. The hand control is attached to the lift by way
of a rubber airline tubing. Due to the design of the lift system, it takes very little effort to press a button to per-
form the desired motion.
Please refer to figures 1A and 1B to see sample floor plans of an installed lift system. Refer to figures 2A and
2B to familiarize yourself with the components of the C450/ C625 lift. Figures 3A and 3B show the underside
view of the lift as it would be seen by an operator.

Cautions

C450/ C625 - User Guide (753101) Rev: 14 MAR 2017 Page: 8
Attaching the airline tube to the lift
Should the gray rubber airline that connects the lift to the hand
control become disengaged from the underside of the lift it must
be re-connected in order for the lift to work properly.
The rubber airline may become disconnected for the following
reasons:
1) The lift is pulled along the track by the airline.
2) The tubing accidentally gets wrapped around an object while
a lift or transfer is being performed.
3) It is accidentally pulled out by the caregiver or the individual
being lifted.
The airline is connected to a grey rubber grommet located on the
underside of the lift. Refer to figure 13A.
Small metal ribbed pins located at the end of the airline hold the
airline to this rubber grommet in a specific manner. Therefore it is
important to make sure that the airline is connected properly.
Both the grey airline and the rubber grommet have a grey rib on
one of their sides. Line up the grey ribs together. Refer to figure
13B. When this is done then the metal ribbed pins attached to the
end of the airline can be re-inserted into the corresponding holes
in the rubber grommet on the underside of the lift. Be sure to in-
sert the pins into the grey rubber grommet sufficiently so that it is
secure. Refer to figure 13C.
Perform a brief test to ensure proper connectivity. Turn the lift
ON and OFF. Raise and lower the carry bar. For motorized trav-
erse lifts move the lift left and then right. If these functions work
correctly then the airline is properly connected.
If the lift does not work properly, check to ensure that the grey
ribs on the grey rubber grommet on the underside of the lift and
the airline tubing are lined up properly. If they are not lined up
properly, then remove the airline, line up the grey lines and then
re-insert it into the rubber grommet. Perform the test as noted in
the preceding paragraph. If there are still problems with the lift
then contact your local authorized dealer for service.
Caution: A sturdy ladder may be required in order to access the underside of the lift to re-attach
the rubber airline of the lift. Caution should be used when this is required.
Should you have any concerns or questions contact your local authorized Prism Medical dealer.

The lift is normally parked at the charg-
ing station end of the track when not in
use. It can be moved along the track to a
position directly above the person to be
lifted in one of two ways.
If you have a manually traversing lift
lower the carry bar to a comfortable
height such that it can be easily grabbed
by your hand. Move the lift along the
track by gently pushing the carry bar, or
individual in the sling. Never pull the
lift along the track.
If you have a motorized traversing lift, use the blue or yellow colored
directional hand control buttons to move the lift. The blue and yellow
buttons correspond to the blue and yellow directional arrows on the un-
derside of the lift. The direction therefore that is taken is determined by
the color of the button that is pressed. This works the same no matter
what side of the lift a person is standing on. Refer to figures 6A, 6B and
6C.
Raising/lowering the carry bar
Operation
By pressing the DOWN arrow
button, or the UP arrow button,
the carry bar can be lowered/
raised to the correct height for
attaching the sling or position-
ing an individual. Refer to fig-
ure 5A and 5B
It is recommended that the care-
giver (operator) hold the carry
bar with one hand while this is
being done so that it will not
accidentally sway and/or come
into contact with an individual
or close object. These buttons
work the same on each model
of the lift.

Operation
Moving the “H” system traversing beam
If the installed track is an “H” system then this sec-
tion should be reviewed as it describes how to move
the traversing beam. If the installed track is not an
“H” system then this section can be skipped.
The “H” system involves the installation of two par-
allel support tracks and one traversing beam that is
mounted perpendicular to the two support tracks.
Refer to figure 7A. The benefit of this type of system
is that it provides greater movement and positioning
ability for an individual since the floor space cover-
age area is much higher than for a single piece of
track.
Besides the previously described UP/DOWN move-
ment of the carry bar, and LEFT/RIGHT movement
of the lift, the “H” system adds the ability to move
the traversing beam anywhere along the length of
the two parallel support tracks. Refer to figure 7A.
Figure 7A - Sample of “H” system room covering layout. Note that the
lift can be moved along the traversing beam, and that the traversing
beam itself can be moved along the two parallel support tracks.
The actual direction of travel when the hand control buttons are pressed
may be different than shown, since the track and lift orientation may be
different than installed. .

This can be accomplished in one of
two ways. If the installed “H” trav-
ersing beam is
manually traversing then the
beam is moved along the support
tracks by manually moving the
beam, lift, and individual in one mo-
tion. This movement is the same as
that used for a manual traversing
lift, as previously described.
If the installed “H” system travers-
ing beam is motorized traversing
then the beam is moved along the
support tracks by pressing either the
black or white hand control button. Refer to figure 7B. This will move the beam
in the direction of travel as noted by the black [▼] and white arrows [▲]located
on the underside of the lift. Refer to figure 7C.

Caution: Always use extreme care when moving the traversing beam. Watch out for and
avoid any obstructions that may cause injury to the individual in the sling, or damage to the lift/
Caution: Do not operate the lift , with bottom cover open.

C450/ C625 - User Guide (753101) Rev: 14 MAR 2017 Page: 12
Return To Charge (If Equipped)
If your motorized, traversing lift has a return-to-charge feature
(RTC), pressing & holding the blue and yellow colored directional
hand control buttons simultaneously for 3-5 seconds (to produce beep-
ing noise) will automatically retract the lift’s carry bar and drive the
lift along its track until it docks at the charger.
The new weight sensitive adaptive return-to-charge feature offers
added protection during RTC movement. The salient features of new
“Load Sensitive RTC” are as under
1) If user/operator may have accidentally enabled RTC while a pa-
tient is in the lift , the RTC function will stop automatically by
sensing excess load on the lift during RTC. The overload threshold
is between 35-50 lbs. (15.8-22.6Kg).
2) During RTC, if lift carry bar accidentally gets tangled with obsta-
cles , furniture , drapery etc., the lift will automatically detect the
change in the load and if any variation of more than 15-30 Lbs.
(6.8-13.6Kg) is detected the lift will stop automatically.
Note:- RTC feature can always be interrupted manually by either
pressing any buttons on the hand control or by holding the carry
bar firmly as shown in figure.
Note that the RTC feature has several characteristics that may be al-
tered to the user’s preference:
RTC Max. Time may be set anywhere from 60 sec to 240 sec in 60 sec
increments and represents the maximum time allowed for the lift to
travel to and dock at the charger before aborting the operation.
RTC Drop Time may be set anywhere from 3 sec to 24 sec in 3 sec
increments and represents the time the lift devotes to lowering the car-
ry bar upon docking at the charger.
RTC Speed may be set to 2, 4, 6, or 8 and represents the relative speed
the lift travels at to reach the charger.
Contact your Service Technician to change these settings.
Caution: Always ensure the carry bar is attached to the lift before activating RTC function. The
added weight of the carry bar is required to ensure correct working of limit switches. Failure to
have carry bar attached can result in limit switch error , refer to “Troubleshooting” Section at page 25
for recommended solution.
Caution: Always use extreme care when moving the traversing beam. Watch out for and avoid
any obstructions that may cause injury to the individual in the sling, or damage to the lift/track.

C450/ C625 - User Guide (753101) Rev: 14 MAR 2017 Page: 13
Basics in transferring an individual
Caution: Always check to ensure that the lift is correctly positioned directly above the per-
son to be lifted. Over time, the lift strap may fray if this is not followed.
Caution: Always make sure that the sling is correctly fitted and adjusted on each side of the
individual so that maximum comfort and safety are achieved prior to lifting.
Step 1) Move the lift away from the charging station or current location and close to the individual that is to be
transferred. Use the procedures for up and down and moving along the track as described in the sections titled,
“Raising/lowering the lift” and “Moving the lift along the track”.
Step 3) Once the individual has been outfitted with the sling, move the lift so that it is positioned directly over
the individual. Lower the carry bar to a height so that the straps of the sling can be easily attached to the carry
bar.
Caution: The following steps are intended to generally illustrate the procedure involved in the lifting
and transferring of an individual from one location to another using the lift, track and sling. Track con-
figurations will vary by installation.
The manual for the sling that was purchased with the lift should be reviewed in detail prior to attempt-
ing these steps, as the sling illustrated here may not be the same as the one that was purchased.
Contact your local authorized Prism Medical dealer if you have any questions or concerns.
Step 2) Prepare the individual being transferred with the appropriate sling. Refer to the instructions supplied
with the sling that was purchased on how to properly outfit an individual with a sling.
Caution: Always use extreme care when moving the lift along the track. Watch out for and
avoid any obstructions that may cause injury to the individual in the sling, or damage to the
lift/track.
Caution: Check to ensure that the carry bar has no cuts, dents or sharp edges that may
come in contact with the straps of the sling and cause damage to them. Report any concerns to
your local authorized dealer.

Caution: Prior to lifting an individual make sure that the straps of the sling are securely
placed on the hooks of the carry bar and that the straps will not come off.
Step 4) Attach the straps of the sling to the hooks of the carry bar. The straps on each side of the sling are gen-
erally attached to the corresponding side of the carry bar. Be sure to double check to ensure that the straps are
properly attached to the carry bar, and that the individual being lifted is properly positioned in the sling prior to
lifting.
Caution: There is a risk for the strap to disengage from the hook, if a sling loop is allowed to
rotate and rest on the top of the hook(s). Please check to ensure that the loops are on the hook
not resting in the hook. Failure to adhere to these instructions could result in serious injury or
death.
For your safety and the safety of the patient, please always ensure that the sling loops are correctly
positioned on the carry bar hooks. It is suggested to do the check of the sling loops once there is
tension to the sling loops, but prior to completely lifting the patient.
Caution: Prior to lifting an individual ensure the hand control cord is free of the carry bar
hooks.

Basics in transferring an individual … continued
Caution: Prior to removing the straps of the sling from the carry bar be sure to check that
the individual being lifted is securely supported in the final desired position.
Step 8) Lower the carry bar sufficiently to allow the straps of the sling to be easily removed from the carry
bar. Take care not to let the carry bar come in contact with the individual in the sling. The straps from the sling
can now be removed from the carry bar. The carry bar of the lift should then be raised sufficiently and the lift
moved away from the immediate area so that it will not interfere with the removal of the sling from the indi-
vidual.
Step 7) Once at the desired location the individual in the sling can be lowered/raised to the correct height in
order to complete the transfer. On completion of lowering/raising ensure that the individual is properly posi-
tioned and safely supported prior to removing the straps of the lift from the carry bar.
Step 6) Once at the correct height the individual can be moved along the track to the desired location. Refer to
the sections already described in this manual on how to move the lift along the track
Step 10) The lift can now be moved to a safe location until further use, or relocated to its' original location.
The lift should be turned off when not in use. It is recommended that the lift be left on charge when not in op-
eration. Refer to the section titled, “Charging the lift” for instructions on charging.
Step 9 ) The sling can now be gently removed from the individual. It should then be stored in a safe place for
future use.
Optional Hand Control Hook
Your lift has come with an optional Hand Control Hook. This Hand Control Hook can be installed onto the
Hand Control using the self tapping screws provided with the plastic hook. On the back of the Hand Control
there will be 2 small pilot holes where the self tapping screws should be screwed into. See figure 7D for a
Hand Control with the Plastic Hook already assembled. Figure 7E demonstrates the use of the plastic hook
with your lift.
Figure 7D - Hand Control with Hook Figure 7E - Suggested use
Step 5) The individual may now be raised with the use of the UP button on the hand control. While lifting is
in progress the height required in order for the transfer to be completed safely should be closely observed. En-
sure that the individual being lifted will not be injured by any obstructions during the initial lifting.
Caution: Always use caution when lowering/raising an individual who is in the sling of the
lift. Watch out for and avoid any obstructions that may cause injury to the individual, or dam-
age to the lift.

Charging the lift
When the batteries are low and require charging
the light will turn ORANGE on the lift control
panel and an audible alarm will beep every 10 sec-
onds. Complete the transfer that is in progress and
then move lift to the end of the track where the
charger is located.
When the batteries are fully discharged the light
will change to RED on the lift control panel and
the audible alarm will beep every 10 seconds. The
display screen will also FLASH “Low Batt!”.
Note: When the battery is discharged the UP
function will be disabled. If the up button is
pressed the display will show Low Batt! on the fist
line and UP:INHIBITED! on the second line. The
DOWN, EMERGENCY DOWN and X-Y
TRAVERSING will continue to operate.

charged battery indicator light and audible alarm

Display Screen
The charger contacts with two metal charging strips that run along the inside of the track.
Whenever the lift is over a section of track with charging strips it will automatically start to charge
the lift if its battery is low.
The batteries should be charged on a regular basis. It is recommended that the lift be left on charge
when not in operation, and at the end of each day. This will maximize the life cycle of the batteries
The lift may remain connected to the charger indefinitely since the charger has a built-in regulator,
eliminating the danger of overcharging.
As a general rule it is recommended that the carry bar be raised to a height so that it will not
interfere with anything or anyone while the unit is not in use.
When the lift is on the charger the light on the lift will always be ORANGE. After one hour, the lift
may be used, however, overnight charging is recommended. The light will change to GREEN when
the lift is removed from the charger. This indicates that the lift is charged between 25%-100%.
Caution: Unit can be isolated electrically from “Mains” by unplugging the charger.
Caution: Do not position the lift in a position where it is difficult to disconnect the charger in an event
of an emergency.
Caution: Power supply is considered as a part of C-625/C-450 system Use only the charger that was
supplied with the lift. Use of any other charger will void all warranties and may cause damage to the lift.
Note: The lift can be charged with the lift in ON or OFF position.

In addition to the indicator lights on the lift, the
charger has an indicator light as well. When
ORANGE, it indicates that the that the lift is on
the charger and charging. Refer to figure 9A.
When the lift is fully charged light on the
charger will change to GREEN.
Note: In some circumstances it may be neces-
sary to mount the charger out of view.
Figure 9A - Charger with ORANGE light indicating that the
lift is connected and charging. When the lift is fully
charged this light will turn GREEN.
Constant Charger
The constant charger system has two
metal roller bearings (Figure 9B) that
contact charging strips that run along the
inside of the track. When the lift is over
a section of track with charging strips it
will automatically start to charge and the
light be ORANGE.
Note: Constant charge units don’t turn
off, since they are constantly connected
to the charger.
The constant charger can be attached to all operating C-450 or C-625 lifts. The batteries can
remain connected to the charger indefinitely, since the charger has a built-in regulator, the danger
of overcharging is eliminated.
